Kiehl's Since 1851 Vital Skin-Strengthening Super Serum

Kiehl's NEW skin-strengthening serum helps protect against skin-aging stressors and visibly corrects signs of aging.

WHAT IT IS?
Skin-strengthening serum penetrates skin up to 8 surface layers deep* to help correct signs of aging through visibly diminishing fine lines and reviving tired-looking, dull skin, which can be caused by skin-aging stressors. Formulated with 11kDa Hyaluronic Acid — our smallest form of Hyaluronic Acid — and a proprietary Adaptogenic Herbal Complex, our potent “super serum” deeply penetrates skin’s surface layers** and neutralizes skin-aging stressors to visibly renew skin.

*Based on a clinical study of 25 panelists measuring the penetration of the full formula via tape stripping.

**Stratum corneum layers.

WHAT IT'S GOOD FOR?

• Strengthens skin from within its deep surface layers
• Protects against stressors including sun exposure, pollution, stress, lack of sleep, diet and temperature that can lead to early signs of aging
• Visibly reduces fine lines, improves resilience and boosts radiance for glowing, healthy-looking skin
• Absorbs easily with a lightweight texture
• For all skin types, including sensitive skin

KEY INGREDIENTS:

11kDa HYALURONIC ACID
Kiehl's smallest molecular size of Hyaluronic Acid, this micronized ingredient penetrates skin to deliver skin-strengthening hydration. 11kDa Hyaluronic Acid helps better retain moisture for improved resiliency, suppleness and bounce.

ADAPTOGENIC HERBAL COMPLEX
Adaptogenic Herbal Complex is a proprietary blend of adaptogens — Red Ginseng Root, Holy Basil and Schisandra Berry — traditionally used in Traditional Chinese, Korean and Ayurvedic Medicine. Within our formula, these adaptogens work synergistically to defend skin from stressors while renewing and resurfacing skin’s texture for a smooth, radiant appearance.

HOW TO USE:

• Apply skin-strengthening serum onto cleansed face and neck, morning and night
• Can be used under another serum and/or moisturizer
• Avoid contact with eyes
• If contact occurs, rinse thoroughly with water
